Obviously I have a Berk single header back that I'm trying to fit to my AP1. BT1604-TP-AP1

Berk sent 2 AP2 hangers that I assume go on the muffler itself and use the existing AP1 hangers at the other locations.

The exhaust is VERY close to the rear subframe tube and the 1/2 shaft cups. I also have some 1/2 shaft spacers that probably aren't helping. If I can lower the rear section of the exhaust from the car I can avoid these 2 small issues but the existing hanger in front of the rear axle prevents this. Use another AP2 hanger to lower it?

I REALLY want this exhaust to work as I love the way it looks.

 

Put the AP2 hangers, long ways, at both ends of the exhaust. One at the last hanger before the muffler exit and one where it connects to the header.

 

What did you do at the muffler, axle side and at the hanger that hangs off the diff collar? AP1s?

 

I used the AP1 hangers at the other locations. Using the AP2 hanger nearest the header will provide enough drop to clear the axle cup. Using the other AP2 hanger at the muffler tip will clear the bumper. The AP1 hangers everywhere else till hold it tight enough not to wobble. The spacers you are using might make it a tight fit. You could purchase a third AP2 hanger and use it at the other muffler hanger and if you point the triangle side in it will help push against the frame of the car and prevent movement.

 

Thank you thus far, this is helping a bunch!!

 

I dont know why you would need more hangers than what they gave you. Use all the hangers provided including an extra that goes on the the diff collar bolts. You will need to use the two bols from the diff collar to mount the additional hanger they give you. done!
This will give you enough clearance and keep it rock solid.

 

S2000ellier was just giving me options or rather direction as to what he did and WHERE he put the AP2 hangers that Berk gives you. It would be nice if Berk gave you some direction on what to do with the hangers they now provide.....they designed it and included those for a reason. They should be kind enough to show you where to install them and share their intentions.

After following S2000elliers advice, yes, the exhaust was rock solid BUT with my 1/2 shaft spacer I had contact with the 1/2 shaft cup bolts at the differential.

I will remover my spacers this coming weekend to try to eliminate the contact.

 

It's a tight fit for sure. I had to readjust and switch around the hangers several times to get it right. granted I have an AP2, but the exhaust and position under the car shouldn't be much different.

 

Can you buy the additional differential collar hanger seperate??
